EPA Finds Modded Diesel Trucks Are Causing Higher Pollution Levels

After reading that title, chances are you’re not surprised. The EPA, or Environmental Protection Agency, is a common term we hear in the diesel industry. Even with minimal involvement, you know that the EPA has been after companies that can modify emissions systems and has also cracked down on engine manufacturers for years.

A recent study by the EPA, which was first reported by the New York Times, shows that an estimated 550,000 diesel-powered pickup trucks have had the factory emissions systems either removed or modified in some way over the last decade using aftermarket tuning devices. In fact, they’re claiming that with that many trucks, that results in 5,000 tons of particulate matter and 570,000 tons of excess nitrogen emitted in their lifetime.

I’m not a scientist. I can’t tell you if those numbers are right, but I’m curious to see what you guys think.  I know that they say some devices are illegal, but I guess I never realized how serious the charges were for companies that develop them. Per the NY Times, a mom-and-pop shop in Florida settled with the EPA on an $850,000 charge for selling illegal diesel tuners.

If you want to stop the sales and development of diesel tuners, that is one way to do it. I understand why some modify their trucks, though. Better performance, better mileage, better in many different areas. What are your thoughts on this? Let us know in the comments below. For more, stay tuned to Diesel Army.
